The Protestant Cemetery (Italian: Cimitero protestante), officially called the Cimitero acattolico ("Non-Catholic Cemetery") and often referred to as the Cimitero degli Inglesi ("English Cemetery") is a cemetery in Rome, located near Porta San Paolo alongside the Pyramid of Cestius, a small-scale Egyptian-style pyramid built in 30 BC as a tomb and later incorporated into the section of the Aurelian Walls that borders the cemetery. Mediterranean cypress trees and other foliage in the cemetery cause it to mirror the more natural style of cemeteries seen in the lusher regions of northern Europe. As the name of the cemetery indicates, it is the final resting place of non-Catholics (not only Protestants or English people).

The earliest known burial is that of an Oxford student named Langton in 1738. The most famous graves are those of the English poets John Keats (1795–1821) and Percy Bysshe Shelley (1792–1822). Keats died in Rome of tuberculosis. His epitaph, which does not mention him by name, is by his friends Joseph Severn and Charles Brown: "This grave contains all that was mortal, of a YOUNG ENGLISH POET, Who on his Death Bed, in the Bitterness of his Heart, at the Malicious Power of his Enemies, Desired these Words to be engraven on his Tomb Stone: Here lies One Whose Name was writ in Water." Shelley drowned off the Italian Riviera and was cremated on the shore near Viareggio. His ashes were interred in the Protestant Cemetery; his heart, which his friend Edward John Trelawny had snatched from the flames, was kept by his widow Mary Shelley until her death and buried with her in Bournemouth.
